I do not know what PIF PAF is. But basically I would answer no to your question. They may have an effect on their metabolism, but I doubt they will kill bacteria. That is why disinfectant and pesticide are not the same thing

the simplest way to kill bacteria is to make its surroundin hypertonic...for example by adding large amount of salt(commn salt)...as the outside conditions become hypertonic the bacteria will shrink and hence die..

Use Azadiracta indica juice with a good ditergent to spray wash ur plants...best for their health. Get rid of bacteria & viruses too. If you add haldi powder to it then it will kill fungi too atleast the ones where the spray reaches.
